Hi Erin, I'm glad to assist you. Upon checking, we do not carry a direct-fit mirror set with blind spot detection for your 2013 to 2015 Mercedes Benz GLK250.

Hi Brittney, I'm glad to assist you. Unfortunately, no. We don't do painting on our body parts and only ship them primed. We suggest having it painted locally so they can correctly match the shade of your paint. I hope this helps, but if you're interested in this mirror, you can click on the link below for direct ordering to take advantage of our ongoing sale and limited stocks. Happy shopping. https://www.carparts.com/mirror/kool-vue/mz36er-s?can=CPAE1047

Hi Leo, Yes, this mirror is primed and paintable. A primer or undercoat is a preparatory coating put on materials before painting. You can use it as it is up to such time that you can have it painted, which is still highly advisable. Our return period is indeed 90 days but, to eliminate that problem it is better to follow our application guide for the accuracy of fitment. On the Homepage, please enter (complete) your vehicle’s year, make, model, sub-model, and engine type, and type the part's name in the search box. Once your application is selected, you’ll see a “Guaranteed to Fit” badge if the part will fit, and we recommend that you also double-check Your Vehicle Fit Details as well as the Vehicle Fitment Information table on the product page.
